Assume that there are 10 red balls.

**Before removing the balls from the bag**

Number of red balls=10=2×X ;then X=5

Number of white balls=8×5=40.

Number of blue balls=3×5=15.

**After removing balls from bag**

Number of white balls=40-10=30.

Number of blue balls=15-10=5.

The new ratio is white:blue:red=

30:5:10=**6:1:2**
